Embodiment 1

[0052] The novel box change of the embodiment of the present invention, the novel box change includes:

[0053] a box body, the box body includes a first chamber, a second chamber and a third chamber isolated from each other;

[0054] A high-voltage switchgear, the high-voltage switchgear is arranged in the first chamber, and the output high-voltage power is sent to the transformer for step-down (or the boosted high-voltage power output by the transformer is sent to the high-voltage switchgear); as Figure 1-2 As shown, the high-voltage switchgear includes:

[0055] The switchgear and the operation panel 211 are all existing technologies in the art, and will not be described in detail here.

[0056] The closed container 251 is welded as a thick steel plate, the closed container is arranged on the rear side of the operation panel, and the inside is filled with insulating gas, such as sulfur hexafluoride, and the switchgear is arranged in the closed container;

[0057] A linka...

Embodiment 2

[0078] An application example of the new box-type transformer according to Embodiment 1 of the present invention.

[0079] In this application example, the high-voltage switchgear: the insulating gas uses sulfur hexafluoride, and its insulation performance is higher than that of air; the sensor uses a pressure sensor and a concentration sensor. The inside of the container is connected; the concentration sensor is an electrochemical sensor, which is set on the closed container, and the output concentration is displayed on the reading meter on the operation panel, which can be the digital display of the display or the display of the scale meter; the operating part It is in the shape of "T", the longer part is used as a wrench, and the shorter part has a matching part, which matches the operation end of the linkage mechanism on the operation panel; so that when the matching part matches the operation end, the wrench can be rotated to realize Operation of switchgear: closing or op...

Abstract

The invention provides a novel box transformer. The novel box transformer comprises a high-voltage switch cabinet, a transformer, a low-voltage switch cabinet and a lighting device, wherein the high-voltage switch cabinet, the transformer and the low-voltage switch cabinet are respectively arranged in a first chamber, a second chamber and a third chamber which are partitioned in a box body, the lighting device is arranged in the first chamber, the second chamber or the third chamber and comprises a support piece, a switch and a lighting lamp, the support piece is arranged at an inner side of a door frame, the switch is arranged on the support piece and is provided with an operation piece, the operation piece is used for making the switch switched off by push of a chamber door when the chamber door is closed and making the switch switched off when the chamber door is opened, the lighting lamp is fixed on an inner wall, and the switch is used for controlling the lighting lamp to be turned on and turned off. The novel box transformer has the advantages of good safety performance, small size and the like.

Description

technical field [0001] The invention relates to a switch cabinet, in particular to a novel box transformer. Background technique [0002] At present, the basic structure of the switch cabinet is: cabinet body, handcart, and the grounding of the handcart is through the fixed cabinet body. The light in the switch cabinet is poor, especially at night. If no additional lighting facilities are provided, the equipment inside cannot be seen clearly, which can easily cause safety accidents. Using the switchgear exposed in the space, the insulation performance of the air is not good, and it is necessary to set a longer distance to meet the insulation requirements, which increases the volume of the switchgear accordingly. Contents of the invention [0003] In order to solve the shortcomings in the above-mentioned prior art solutions, the present invention provides a new type of box-type transformer with good safety performance, small size and good grounding performance. [0004] T...
